Mosan
If you got this nick name, believe me. You're the nicest person standing on earth. You'll deny it tho. Whatever. You can camouflage like chameleon (they don't even know who the real you!). Full of chemistry, dry humor, and moody. Like to criticize before agreeing something. Get bored easily. You can make someone feel the warmth only from the words. You're such a guy that can make someone glad to know you.
Mosan will get mad if you disobey his orders. But, he'll give you food and feel sorry about that.
